We report a high-resolution x-ray study of a model multilayer fluid membrane system in the lyotropic L_ phase of a quaternary microemulsion system. The structure factor exhibits power-law behavior characteristic of a Landau-Peierls system. As a function of intermembrane distance 3. 8 nm16. 3 nm, the exponent (d) which describes the algebraic decay of layer correlations is predicted by the model of Helfrich where entropic steric repulsions dominate intermembrane interactions.
